The function and advantage of the OTDR OLT optical module
No CommentsThe fiber to the home (FTTH) is an important technology of the wired access broadband in 21 century. And PON represents one of the most widely deployment network architecture. At present, the global telecom operators are trying their best to reduce the operating network cost. At the same time, they [ Continue reading…]
The transmission distance of our fiber optic transceivers ups to 120km
No Commentshttp://www.fiber-mart.com/fiber-optic-transceivers-xfp-transceivers-c-1_83.htmlAccording to the forecasts of Infonetics, the 100G optical transceiver sales will be doubled in the next two years; and the outlook of many other high-speed modules will be good too.But the QSFP+ enterprise applications are also in good uphill stages. Infonetics expected that the shipment of the 40G QSFP+ [ Continue reading…]
something about optic fiber Splicing
No CommentsA splice is a device to connect one fiber optic cable to another permanently. It is the attribute of permanence that distinguishes a splice from connectors. Nonetheless, some vendors offer splices that can be disconnected that are not permanent so that they can be disconnected for repairs or rearrangements. The terminology can [ Continue reading…]
BASIC CABLE DESIGN
No Comments1 – Two basic cable designs are: Loose-tube cable, used in the majority of outside-plant installations in North America, and tight-buffered cable, primarily used inside buildings. The modular design of loose-tube cables typically holds up to 12 fibers per buffer tube with a maximum per cable fiber count of more [ Continue reading…]
What’s the best way to terminate fiber optic cable?
No CommentsWhat’s the best way to terminate fiber optic cable? That depends on the application, cost considerations and your own personal preferences. The following connector comparisons can make the decision easier.Epoxy & PolishEpoxy & polish style connectors were the original fiber optic connectors. They still represent the largest segment of connectors, in both [ Continue reading…]

The Ports On CWDM and DWDM MUX/DEMUX
No CommentsIt is quite common to use CWDM or DWDM to increase the existing fiber optic network without adding any fibers. Using WDM MUX/DEMUX is necessary to build a CWDM or DWDM network. Now there are different ports installed on the CWDM and DWDM MUX/DEMUXs to add more beneficial to the fiber optic [ Continue reading…]
Guideline for Copper Cabling Installation
No CommentsCopper cabling has been in use since electricity was invented and its quality has continued to improve. Network managers pick copper cabling for various reasons. For instance, copper cables, especially UTP cables, are as inexpensive as optical fibers and easy to install. Moreover, the installation methods are well understood, and the components [ Continue reading…]
Common Types Of Fiber Optic Cables And Patch Cables
No Comments1.FTTH Fiber Optic Cable FTTH (Fiber To The Home), as its name suggests it is a fiber optic directly to the home. Specifically, FTTH refers to the optical network unit (ONU) mounted on home users or business users, is the optical access network application type of closest to users [ Continue reading…]
Typical Outdoor Fiber Optic Cables
No CommentsFiber optic cable provides protection for the fibers from the environment encountered in an installation. Outdoor Fiber Cable is designed strong to protect the fibers to operate safely in complicated outdoor environment, it can be buried directly, pulled in conduit, strung aerially or even placed underwater. While indoor cables don’t have [ Continue reading…]
